The York Federation of Students, which represents the university’s 53,000 undergraduates, said students began bringing the flyers to their attention on Wednesday. The page includes the York University logo, and displays two photos of York sports teams: one is black and white and shows white men only, while the second, more recent picture shows students of various ethnicities.

The flyer is titled “The Changing Demography of York University,” and says that if “mass third world immigration continues, Canadians will be reduced to a persecuted minority, not only at York, but in their own country!! It doesn’t have to be this way!!”

The student federation’s vice-president, equity, Mithilen Mathipalan, said students were “disgusted and appalled” by the flyers.

“York is rich in diversity, and it celebrates that diversity,” he said. “No form of racism or oppression is welcome here.”

Toronto police are investigating.

University spokeswoman Joanne Rider said the posters were actually displayed in mid-July without York’s knowledge or consent, and were removed immediately. She said the university has not received recent reports about the flyers.

York notified the group whose name appears on the flyers, Immigration Watch Canada, to cease and desist from using the university’s logo and photographs.

But Immigration Watch spokesman Dan Murray said his group did not authorize the use of that particular flyer at York. He said Immigration Watch has previously distributed two flyers on campus calling attention to what he called Canada’s high “immigration intake level” that did not bear York photos or its logo.

He said the group is looking into how Immigration Watch’s name ended up on the most recent anti-immigration flyer at York.
